2 Claims.

The present invention relates to new and useful improvements incrossbows and has for its primary object to provide a novel constructionfor securing the bow in position at the outer end of the guide for thearrow and also to provide a novel trigger construction for releasing thebow string when it is desired to shoot the arrow.

A still further object of the present invention is to provide a safetyhook adapted for engaging the bow string to prevent accidental dischargeof the arrow and also to provide an adjustable sight adapted to improvethe accuracy of the weapon when shooting the arrow at various distances.

A still further object is to provide a device of this character ofsimple and practical construction, which is eflicient and .reliable inperformance, relatively inexpensive-to manufacture and otherwise welladapted for the purposes for which the same is intended.

Other objects and advantages reside in the details of construction asmore fully hereinafter described and claimed, reference being had to theaccompanying drawings forming part hereof, wherein like numerals referto like parts throughout and in which:

Figure 1 is a top plan view.

Figure 2 is a side elevational view.

Figure 3 is a fragmentary perspective view showing the arrangement ofthe trigger, safety hook and adjustable sight at the rear end of thearrow guide.

Figure 4 is a sectional view through the outer end of the arrow guideshowing the set screw provided for securing the bow in position therein.

Figure 5 is a perspective view of the trigger and Figure 6 is a similarview of the bow string setting hook.

Referring now to the drawings in detail wherein for the purpose ofillustration I have disclosed a preferred embodiment of the inventionthe numeral 5 designates the crossbow generally which includes the stock6 and the forwardly projecting arrow guide 7 which extends in aforwardly projecting position at the front end of the stock and isprovided in its upper surface with the longitudinally extending groove 8forming the guide for the arrow 9 when seated in the groove.

At the front end of the arrow guide is a transversely extending openingIll through which the bow ii is inserted and secured in position bymeans of a set screw l2.

The rear end of the arrow guide 8 is provided with a metal plate Itlikewise having the groove ll therein in longitudinal alignment with thegroove 8, the rear end of the arrow guide and the plate being formedwith a transversely extending shoulder I5 adapted for engagement by thebow string l6 as shown to advantage in Fig. 3 of the drawings. The sideedges of the plate I5 are provided with downturned flanges ll engagingthe opposite sides of the arrow guide l and secured thereto by means ofscrews or the like it.

In the region of the shoulder IS the arrow guide I is provided with atransversely extending pin l9 on which is pivotally mounted the triggerdesignated generally at 20. The trigger member includes a Y-shaped endportion 2| including the hand grip 22 and the fork members 23 which aredisposed at opposite sides of the arrow guide 7, the ends of the forkmembers being provided with eyes 24 which are pivoted on the pin l9.Projecting rearwardly from each of the eyes 24 is a bow string releasingarm 25, the arms being positioned at opposite sides of the arrow guideand extending rearwardly with respect thereto in a position immediatelybeneath the bow string 86 as shown in Fig. 3 of the drawings.

From the foregoing it will be apparent that a rearward movement of thehand grip 22 will raise the arm 25 upwardly and release the bow stringi6 from the shoulder 65.

Also pivoted to one side of the cross bow is a hook member 28 adaptedfor movement into a position for engaging the bow string it to securethe same against accidental displacement from the shoulder it.

When it is desired to draw the bow string for engagement over theshoulders 85 a double hook member 2! is employed having spaced hooks 28formed at one end thereof and having itsintermediate portion formed withan eye 29 to which a full chain 29' is attached whereby to engage thebow string at spaced portions by the hook member 28 for drawing the sameinto position over the shoulder 85.

The upper edge of the cross bow immediately rearwardly of the shouldersis inclined upwardly and rearwardly as shown at 3t to a point slightlyabove the horizontal plane of the upper edge of the arrow guide 8, therear portion of the inclined section 30 terminating in an abruptshoulder 3!. A sight groove 32 is formed in the inclined section 30 inalignment with the arrow groove 8 and pivoted to one side of the stock 6is an adjustable sight 33 in the form of a wire member pivotedintermediate its ends as at at and having one end bent inwardly over theupper edge of the stock as at 35 and provided with a forwardly extendingextremity 36 adapted to lie in the sight groove 32. The other end of thesight constitutes a handle for manipulating the sight in a manner toraise or lower the extremity 38, the pivoted connection for the wirefrictionally retaining the sight in adjusted position.

While the trigger is normally employed to release the bow-string fromthe shoulders IS, the arms of the trigger also are adapted to engage andrelease the safety hook 25.

It is believed the details of construction and manner of operation ofthe device will be readily understood from the foregoing without furtherdetailed explanation.

What is claimed is:

1. A crossbow comprising an arrow guide having a groove in its uppersurface adapted to receive an arrow, a shoulder at the rear end of thegroove, a bow secured at the front end of the arrow guide, said bowincluding a bow-string adapted for engaging the shoulder when thebowstring is drawn, a safety hook engageable with the bow-string forreleasably securing the latter from accidental releasing movement and atrigger adapted for releasing the bow-string.

2. A crossbow comprising an arrow guide having a groove in its uppersurface adapted to receive an arrow, a shoulder at the rear end of thegroove, a bow secured at the front end of the arrow guide, said bowincluding a bow-string adapted for engaging the shoulder when thebowstring is drawn, a safety hook engageable with the bow-string forreleasably securing the latter from accidental releasing movement and atrigger adapted for engaging the hook for releasing the same from thebow-string and also adapted for releasing the bow-string from theshoulder.
